HAZARD...Flash freeze on roads. Whiteout conditions with near zero visibility associated with intense bursts of heavy snow and gusty winds leading to blowing snow. Wind gusts greater than 50 mph could knock down tree limbs and blow around unsecured objects. SOURCE...Radar indicated. IMPACT...Dangerous and life-threatening travel conditions are expected to develop rapidly in the warning area. This will impact Interstate 15 between Mid Canon and Sun Prairie, or between mile markers 219 and 286. Locations impacted include... Great Falls, Cascade, Belt, Black Eagle, Wolf Creek, Monarch, Sluice Boxes State Park, Eden, Malmstrom Afb, Stockett, Tracy, First Peoples Buffalo Jump State Park, Centerville, Tower Rock State Park, Armington, Craig, Ulm, and Sand Coulee. Wet roadways will quickly freeze. Black ice will cause roads, bridges, and overpasses to become slick and dangerous. Slow down and be prepared for a sudden loss of traction. Consider avoiding or delaying travel until the snow squall passes your location. If you must travel, use extra caution and allow extra time. Rapid changes in visibility and slick road conditions may lead to accidents.http://www.weather.govAWIPSidentifierSQWTFXWMOidentifierWWUS55 KTFX 172000NWSheadlineA SNOW SQUALL WARNING REMAINS IN EFFECT UNTIL 115 PM MST FOR EAST CENTRAL LEWIS AND CLARK AND CASCADE COUNTIESeventMotionDescription2025-12-17T19:59:00Z...storm...272DEG...93KT...47.49,-111.33 46.98,-112.13snowSquallDetectionRADAR INDICATEDsnowSquallImpactSIGNIFICANTBLOCKCHANNELEASBLOCKCHANNELNWEMEAS-ORGWXRVTEC/O.CON.KTFX.SQ.W.0005.000000T0000Z-251217T2015Z/eventEndingTime2025-12-17T13:15:00-07:00WEAHandlingImminent ThreatCMAMtextSnow Squall Warning til 1:15 PM MST.
